<P class="title">"Show information" command<hr></P>

<P>This command is accessible both when WinRAR is in the file management
and in the archive <A HREF="HELPShellModes.htm">management modes</A>.
Just run "Show information" command using either <A HREF="HELPToolsMenu.htm">
Tools menu</A>, "Info" button on the toolbar or Alt+I keyboard shortcut.</P>


<P>In the file management mode it allows to get the information about
contents of selected files and folders: the total size, a number of
files and subfolders, a number of archives. To improve the operation
speed archives are detected basing only on the file name extension,
so <A HREF="HELPArcSFX.htm">self-extracting</A> archives are not counted
here. File scanning may take a long enough time, but if you wish you
may close the dialog in any moment.</P>

<P>Disk space is allocated to files in fixed size blocks called clusters.
For example, if a cluster size is 4096 bytes and you created a file
only 1 byte size, in fact it will occupy 4096 bytes. So, to give you
a hint, how much space your files are really take and how much you
may save after archiving them, the information dialog also displays
a cluster size for the current disk, a real size of selected files
including not filled tails of clusters and so called "Files slack"
- the total space wasted in these cluster tails.</P>

<P>When the file scanning is complete, you may press "Estimate" button
to get a prognosis about compression size and time for selected files.
This prognosis is based on RAR "Normal" compression method supposing that
disk is fast and time spent to disk data exchange is small. Compression
estimation is performed very quickly and very roughly, so do not expect
an exact result here. Though it can show if it is worth spending time
to compress selected data. If you set "Start automatically" option,
the estimate operation will be initiated automatically, when opening
the dialog next time, without necessity to use "Estimate" button.</P>

<P>Also, after completing the scan operation, it is possible to switch
to other pages of this dialog and specify different archive options
like a comment, recovery record, SFX module, etc. It allows to apply
necessary changes to all RAR and ZIP archives contained in the selected
folders and files. Unlike the scan step, self-extracting archives are
also processed here. Be cautious with this operation, it may change
parameters of hundreds and thousands archives at once. Such feature
is powerful, but may become rather dangerous when improperly used.</P>


<P>In archive management mode, when you activate "Show information"
either inside of archive or outside of it, but when only one archive
is selected, WinRAR will display the following information about archive:</P>

<ul>
  <li> archive name (in the dialog title);</li>
  <li> archive type (<A HREF="HELPArcSolid.htm">solid</A>, <A HREF="HELPArcSFX.htm">
    SFX</A>, <A HREF="HELPArcVolumes.htm">volume</A>) and format (<A HREF=
"HELPRARVersusZIP.htm">RAR, ZIP</A>, CAB, ARJ, LZH, etc.). All these
    parameters are combined in the single string displayed at the top of
    the dialog. </li>
</ul>
<P>For RAR volumes created by WinRAR 3.40 or higher this string also
includes a volume number. This number may be useful if original volume
names are lost and you need to restore correct names manually;</P>

<ul>
  <li> minimum archiver version required for extraction. For some archive
    formats, such as ZIPX, this field may also include a name of
    compression algorithm;</li>
  <li> operating system under which the archive was created;</li>
  <li> total number of folders and files;</li>
  <li> total unpacked and packed files length;</li>
  <li> total compression ratio;</li>
  <li> size of <A HREF="HELPArcSFX.htm">self-extracting</A> module
    or zero for non-SFX archives;</li>
  <li> presence of the <A HREF="HELPArcComment.htm">archive comment</A> ;</li>
  <li> presence of <A HREF="HELPArcEncryption.htm">encrypted</A> files;</li>
  <li> if archive is <A HREF="HELPArcLocking.htm">locked</A>;</li>
  <li> <a href="HELPArcRecovery.htm">recovery record</a> size and its percent
    of archive size if recovery record is present. Recovery record size
    roughly indicates the maximum size of continuous damaged area it can
    repair in the best case. For <a href="HELPRAR5Format.htm">RAR 5.0</a>
    archives a percent is the exact value specified when creating
    the recovery record. For older RAR formats it is approximate
    and calculated from the available data.</li>
  <li> maximum <A HREF="HELPGetArcGeneral.htm#DictSize">dictionary size</A> used for any file within the archive.</li>
  <li> original archive name and time if available. They can be added to
    a new or existing archive with appropriate options on
    <a href="HELPGetArcOptions.htm#SaveOrig">"Options" page</a> of archiving
    dialog or <a href="HELPInfoOptions.htm#SaveOrig">"Options" page</a>
    of "Show information" command.</li>
</ul>
<P>If the archive has an archive comment, an additional dialog sheet
containing this comment is displayed.</P>

<P>Like in the file management mode, it is possible to switch to other
pages of the dialog and specify different parameters for the current
archive. Just press "Help" button in other pages to read more about
them.</P>
